Answer:

not enough information

make sure the question is correct

Explanation:

parthassarkar77: All info are perfect ...its FIIT JEE prob from foundation course material ...

Abhijit999: wait a sec i'll try

parthassarkar77: simple ans will be 50 km/hr ...for change of vel ....and for change of speed it would be zero

Abhijit999: velocity and speed is completely different

Abhijit999: change in velocity cannot be zero since change in direction has taken placee

parthassarkar77: true ...thats why change of vel will be 50km / hr ...first it was in north ...so its component along west is 50cos 90=0,...then it turns to west and speed remain same...so vel will be same as speed 50...so change in vel ( 50-0) = 50km / hr

Abhijit999: it seems right
